I would like to summarize ...

Ok I might be asking something stupid, please bear with me, math is not my strong suit. This has to be a duplicate but I dont know how to search them. I dont even know how to word the title, kindly ...

If I have a set of data points with $x$-axis going from $0$ to $2$ and $y$-axis going from $0$ to $1$, how can I get the average $x$-value of occurring? The $y$-axis is probability, but all points do ...

I came across this website showing the proof of the above question in the Expected Value section. However, I do not quite understand why the probability of $xy$ becomes the probability of $x$ (or $y$) ...

I intuitively understand the examples below, but I don't see an "average" in the average rate of change (I see a ratio of two delta values). What is the relationship between the average (arithmetic ...

I was reading Yoshua's Bengio [book][1] on convolutional neural networks and it has small section that described/explains the convolution in the context of estimating the location of a spaceship with ...

If we are comparing maintenance costs (M$) per mile (M$/m = Mtype) of two car models over a 5 year period, where the number of cars that are type (a) is much less than type (b), and the number of type ...

I'm trying to find out the average point between 3 or more points, given each distance that the end point is away from each of the other points.
With 2 points it's easy, I believe the formula should ...

Today is one of those days when the correct method to calculate this escapes me.
I have 3 fixed points on a map where measurement devices are located. These all track the same transmitters. A mobile ...

At a Dental Office, patients come in at the rate of 20 per hour and, on average, are processed at the same rate. Patients wait in a queue till they are called up to the counter for registration. After ...

If I have a table of values in Matlab ( here I have a 40k rows, and about a dozen columns), how can I read only particular values from each row? My goal is to extract some of the values from each row, ...

In a proof I was working on today, I assumed this equation was true which lead to devastating results
$$ \sqrt{\bar{x^2}} =\bar{\lvert x\rvert} $$
For instance, given the data 0 and 2, the left hand ...

I am working in Excel and have two sets of data points that come up with a percentage for the likelihood of a recession. I am wondering what the best strategy would be to combine these data points? ...

Let's say you wanted to calculate, for example, the average (i.e. mean) cost per day for a hotel to accommodate a tourist. If only aggregate cost data is available, is dividing the average cumulative ...

Consider two integers $n \ge m \ge 4$ and $A=\{a_1,a_2,...,a_m\}$ a subset of the set $\{1,2,3,...,n\}$ with the property that
$$\forall a,b \in A \text{ with } a \neq b, \text{ if } a+b \le n, \text{ ...

Let $x_i$ be a positive real variable, with $i=1,2,...,K$.
We denote by $\bar{x}$ the average value of the values $x_1, x_2,...,x_K$. Let $a=\min_i x_i$ and $b=\max_i x_i$, then $x_i \in [a,b]$.
My ...

I am looking for an integer solution to the equation:
$$\frac{a^2+b^2}{2}=c^2(a\neq b\neq c)$$
That is a square number that is the mean of two other square numbers, is this possible? And if so please ...

I have a question about a non-Gaussian distributed parameter that can only take certain values in a defined interval.
Knowing that I have to define this parameter starting from a set of its values and ...
